1LE to Z/28 Wheel Specs
6 Attachment(s)
I acquired a set of used Z/28 wheels that I am going to run on the car with a set of Hankook RS3 (140 treadwear). I figured out the following information for 1LE owners looking to changed to a 305/30/19 tire for the track. ( No, I cant get anymore Z/28 wheels for you :) ) Note: I have a set of used 305/30/19 Bridgestones on the car in the pictures while I was test fitting them and deciding what tire to try....

You of all people should know that we have 20 x 11" rears. ;)

Whats the clearance like on the inside of the rear tires? Can they be brought in a few mm? -3.5 degrees of camber up front tucks a lot of tire from what I've done with camber plates.

In the pictures the car is sitting with -2.0 up front and -1.0 in the rear.
There is 11mm more clearance than the stock wheel on the backside. |
how does it drive ?

How do you like -3.5 degrees camber in the front? How's tire wear on the track? I'm at -2.9 now and since I'm running Hoosiers on the track I'm thinking of going to -3.5 or maybe -4 degrees. I know a racer that is at -5 degrees front but Justice Pete advised that I go -4 max, even for a track-only car. |
I would go with what Pete said he knows his stuff

Looks awesome, where able to find the fender extensions, are those even bolt ons?

http://i154.photobucket.com/albums/s...ps231ad7e5.jpg The reason why you don't want too much camber is keeping things balanced with the rear where you normally run half the front setting. You reach a point and your camber in the rear gets too high and you will have a hell of a time planting the power in straights and powering out of turns. High HP RWD cars will always need to find a balance. If we were mid engined we could push the envelope more. |

You need the 2014 front end to make it work. Been pondering that plus the ACS Z-style spoiler but not sure how to terminate the wheel flares/rocker situation since I have zero interest in a rear end conversion. Might need to make a small custom piece or two out of fiberglass but no time for that.
I'm curious to see what the aero package from GM includes since it seems to be a "partial" setup around the sides of the car. |
